Help Old Performa 6400/200 Boot Up problem

Hey everyone I used to know this but it’s been a while since I’ve use this computer.

I’m having a problem with the PowerMac booting up

These are the different things I get

first it goes to the :-) computer and then stays there

then sometimes it goes to a flashing disk with a? At the center of it

then on booed up I hold the shift key down to disable extensions and it starts to load with the progress bar and then freezes and says system error and stops

this computer used to work I have a lot of stuff on the hard drive there I can’t get it to boot up properly

Hi,

Any change if you try a PRAM reset? Press and hold the four keys Command(Apple) + Option(Alt) + P + R immediately at startup. Release the keys when a second startup sound has been heard.

Do you have access to another startup disk/disc? This could be an appropriate disk tools floppy, or a system CD. If so, you may want to check whether it is possible to complete the startup sequence with that disk/disc.

Also, check the condition of the logic board battery. Furthermore, you could remove and reinstall all cards (including RAM). Check all cables and connectors. Inspect the logic board with a magnifying glass in order to locate possibly leaking/discoloured/cracked electronic components. Bad electrolytic capacitors can cause many problems in old computers.

Do you have access to another old (pre-1998) Mac?

If absolutely necessary, there are other ways to access the data on the hard disk (for example, via an external universal USB bare drive adapter).
